Be it known that I STANLEY W. NICHOL- SON, a citizen of the United States of America, residing at Toledo, in the county ofLucas and State of Ohio, have invented certain new and useful Improvements in Vehicle lVindow-Control Mechanism, of which the following is a specification, referencebeing had therein to the accompanying drawings I vide a simple andvefficientmanually opertlle YR glass in different posi-f Z 'at'I to fornra'stop which limits-downward l g to provide 7a simple 3 and inexpensive, yet efficient, spring means I I p andsgla'ss G-awlien a down. thrust is exerted" upon the-':-stern :Gni:vTo icounterbalance the I,

able mechanism forraising 'or lowern glass in a window of: the slidingglass t and for retaining the tions of adjustment. f A further. object is forlcounter-balancing the 'weight oi' the slid lng'glass. I

more any hereinafter appear; p In" the accompanying drawings a Figure l is an interior view ofa mot'or vehicle doorto which the invention s'ap plied; I

unlocked position of the locking mechanism" resulting from a downward actuation of the control means;

Figure 5 is a similar fragmentary view,

but showing the loclged position assumedby the locking mechanism when no actuating stress 1s exerted. I

In these views the reference character Ag designates an automobile door", the lower portion of which is of the usual "holloworchambered construction, while the upper;

portion is provided with a window opening B and with a vertically slidable plate ofglass C providing a closure for said opening when raised and entering the chambered lower portion of the door when downwardly This inventionrelates to window control mechanisms and more partioularly to con trol mechanisms for automobile andfother vehicles. I i I v It is the object of the'inventiontoflproj" The 1 'vention consists in certain arrange disclosed in the unlocked projects above the detent to adjusted. The lowerlcdge of said plateis embraced a sheetnnetalichannel 'mcmber D, which ssecured to the glass in any desired manner. A locking bar E is pivoted as indicated at F upon-one end of the channel member I), andextends preferably the 't'ulllength of said channel member, the

free end of said bar being pivotally engagedby the lower extremity oia control stem (twliich extends upwardly adjacent one oi position, an flange insuring; upward move- "the-channel niernbertand glasszwhen the aix iijs upwardly actuated by the 4 rod Gt bracket/ 1 secured "to the bar .1?! adj acent': its iree end is changed as indicated swinging ot saidbar and insures a down-'- wardr' actuation "of' the channel; member D vL weight-"019i the". glass, 'there': is monnted .benejath'xthe"same bar J,- one'enduoi which end-to a bracket N u'ponthe post C. With this counter-balancingmeans, there is combined a locking means as follows:

A detent 0, preferably formed of sheet metal is pivotall y'carried by the free end of the bar J and engages beneath the locking barE. I Preferably said detent has aseparately formed; pivot-forming member P which is weldedor-brazed, or otherwise secured to a lateral vface of said detent and engage a pivo pin Q carried by the bar J. Said detent base portion projecting beyond the free end of the bar J, which portion terminates in a tooth R; projecting I upwardly and adaptedto engage a rack of teeth R, formed uponthe lower edgevof the bar E. Adjacent'the tooth B, said detent is formed with astruck out laterally projecting tongue S, which is'curvedtto. engage beneaththe chan- ,65 the side postslj' ot' the door within the I windhwopening-Ba flange-Hon the chanp ncl io i 'einber D forms a" stop 2 limiting upward swingingot the beyond; a horizontal nel member D, so as to limit upward swinging of the toothed end of the detent. Said detent also projec s some distance in the opposite direction beyond its pivot Q, and the upper edge of this last mentioned projecting portion is inclined slightly to the remaining portion of the upper edge, as indicated at T. The roller L is mounted upon the detent O at the opposite side of its pivot Q fromthe tooth 11.

Discussing now the 'operation of the described invention, when an upward pull is exerted upon the rod Gr, the bar E is drawn up against the flange H of the channel member D, -as is illustrated in Figures 2 and 3, the rack teeth R thus being disengaged from the tooth R of the detent. Thus, the channel, member D and glass C are free to move upward responsive to the 'pul-l on the stem (5r, while the detent shi'fts transversely V of sa idc'hann'elmember,theroller L traveling along said member, WVhen a" 'down 'thr-ust is exerted upon the stem G, the barE i's" shifted to the position disclosed in Figured,

During this movement of the, bar E, the dete'n't O is rocked"totheiposition"disclosedin Figure 4, owing to engagement of the upper edge portion T of saiddetent by'theg lower edge 01. the bar E, the tooth It being.

shifted "clear of the rack B, so that the channe'lflmeniber D and glass C -are free to move downwardly, responsive to the irod G,

no resistance being offered to the necessary ,travel'of the detent'flong it-udinally of the,

member "D. When after shiftingthe glass to any desired position 'of'2adjustment, the stem Gr is"rele a'sed, the bar E drops'sli'ghtly below the horizontal position and engagesthe rack R with the "tooth 11 of the detent 0, said detent is maintained in a :position adapting it for such engagement by 'the'upward stress'acting'at the pivot point'Q and causing the roller L and-the stop member S at opposite sides'of said pivot fpo intyto bear upwardly against the channel :member D.

The described construction isone'comprising "relatively few parts, effecting a very perfect counter-balancing of the window,

providing a simple actuating means forthe latter and providing for locking of the win- 1 d ow in practically "any desired position "of adjustment. 4 I
